SOAP for granular particles in compacted environment

[deepakpawar2310]

I'm seeking an application for SOAP (Smooth Overlap of Atomic Positions) to analyze granular samples. The system comprises particle positions and radii, with a compacted arrangement of 10,000 particles, each possessing interparticle contact data such as force and torque, etc. I aim to compare two analogous samples using SOAP under these specified conditions.

One way is to use the coordination number of particles, which is insufficient to compare the similarity of two compacted granular samples (https://link.springer.com/article/10.1007/s40571-023-00659-x).

I recommend using the SOAP descriptor for the same, with the help of a database of each particle.

Is it reasonable to use SOAP descriptors for the same??
I went into detail about SOAP, which involves some complicated computations.
But my system has mesoscopic information about particles.

Is my approach correct? Can you share your experience with the same

Any lead/idea will be appreciated.
